The I/O module provides, on 1 logical channel, 24 bytes input and 24 bytes output
process data to a fieldbus coupler/controller. These consist of 8 control/status
bytes and 16 data bytes.
Notice that the process data image depends on the used fieldbus coupler/
controller!
Mapping the process data into the process image is specific for the fieldbus
coupler/controller used. You will find both this information and the specific
configuration of the relevant control/status bytes in the manual of the
coupler/controller, section "Fieldbus Specific Configuration of Process Data"
which describes the process image.
